IS JUSTIN BIEBER HEADED FOR A BREAKDOWN? 

After showing up late to a show this week, getting booed by fans, and then, collapsing backstage after taking oxygen and then, after going off on a photographer, people are beginning to ask about the boy wonder's mental well being. 

And for good reason. He's been keeping up a frantic work pace for three years now... from tours to studio work for new music to new tours. 

Add into this allegations of different "habits" and the like when it comes to "extracurricular" activities - and a very public breakup with a former girlfriend... it's likely he's starting to crack a bit. 

Not to mention... he's 19... worth billions and rarely hears the word "no..." 

Do you think someone needs to step in? Sure he's famous... but he's a human being... and we've all seen how this story ends....
